My computer configured as follows:

Dell XPS 700

Intel Core2Duo E6700 2.66gHZ 1066 FSB processor

4GB Dual Channel DDR2 SDRAM @ 667mHZ

EVGA Killer NIC Xeno Pro network card

1GB nVidia GeForce 7950 GX2 Dual GPU Graphics Card

Windows 7 Home Premium

I was sitting at the computer about to go into Second Life and right after clicking on the icon, the monitor went into "power save mode" and never came out of it. 

The computer sounded as if it was trying to start, then rebooted itself and never posted to the BIOS screen.  I apologize for not knowing the BIOS version, I think it's 1.14.1 but I'm not sure.  At any rate, the computer just goes into a loop of trying to boot, then it reboots, but it never even reaches the BIOS screen.

My guess is motherboard, processor, or both.  This forum has always been an excellent source for information and knowledge in the past and I'm hoping you guys can help me out one more time. 

Thank you in advance,

Invex
